Winter houseplant care: the lazy guide

4 min read

Plants rest in winter, and so should your watering can. Here's what changes when the heat comes on and the light drops.

Winter turns houseplants into slow, sleepy versions of themselves. The light drops, the air dries out the moment the heating kicks on, and growth crawls to a near-stop. The good news? That means winter care is mostly about doing less — and doing it deliberately.

Less water, much less often

Because plants barely grow in winter, they barely drink. A pothos that wanted water every week in July might be happy every two or three weeks in January. Keep using the finger test — dry an inch down before you water — and you'll naturally stretch the interval without thinking about it.

The classic winter mistake is watering on the same summer schedule, which leaves soil wet for too long and invites rot. If you change one thing this winter, make it this: slow down.

Light is the real winter challenge

Days are short and the sun sits low, so even a bright window delivers a fraction of its summer power. Move light-hungry plants closer to the glass (without touching cold panes), and consider a cheap full-spectrum grow light for anything that's stretching or getting leggy. A plant leaning hard toward the window is literally asking for more.

Watch the dry indoor air

Heating pulls humidity out of the air, and many houseplants — ferns, calatheas, marantas — sulk in dry rooms. Brown, crispy leaf edges are the telltale sign. Grouping plants together, using a pebble tray, or running a small humidifier nearby does far more than misting (which evaporates in seconds and barely helps).

Hold the fertilizer

Fertilizing a resting plant is like forcing a meal on someone who's asleep — at best it's wasted, at worst it builds up and burns roots. Pause feeding from late fall through early spring, and resume when you see fresh new growth return.

Keep them away from the cold

  • Drafty doors and single-pane windows can drop leaves below freezing even in a warm room.
  • Heating vents blast hot, dry air directly — a fast way to crisp a plant's leaves.
  • Most tropical houseplants want 60–75°F; anything consistently below 55°F stresses them.
Winter isn't the season to push your plants. It's the season to keep them comfortable and let them rest. Spring will come, and they'll wake up hungry.

Not sure how much to cut back your watering this winter? Thumbs' watering calculator adjusts for the season automatically — plug in your plant and light, and it'll give you a winter-appropriate interval.
